This illustrated guide does not make anyone an instant expert. We advise that this guide is used by skilled persons & recommend taking pictures at several stages during before dis-assembling, and making notes where necessary. Every care is taken to display and describe details with best explantion & effort. Any inadvertent errors & missed steps will not hold us responsible for any liability for damage or injury.
Recommendation
Please use right tools to avoid damage. Work in well lighted space. Use a stable bench with necessary tools, extra container & rags to clean water spills. Wear rubbe sole shoes/slippers. Unplug power to the machine. No children in the area.

4. Gently pull up the grinding unit from the housing & tilt a slight angle , to see the motor connections from below .The connectors are marked with a (+ve) & a (-ve) label & wires are color coded. Make note of the wire color ( in this grinder : Plus = white; Minus = blue color). If wire colors are different then transparent wire is +ve & black is -ve. Yet other grinder motors may be without any label. To pull the two wires, do not apply force alone. There is a small locking contraption inside the connector. Press it with a small metallic tip to unlock & pull the connectors off easily (see red arrow). In newer models, a heat sensor is installed on one side of the grinder, clamped with a plastic holder. Cut through the cable tie & remove the sensor holder & heat sensor. Now the grinder assembly is ready to be removed.

-Slide the grinder hopper into the guide on the grinder & fix it with screw or cable tie. -Check if the rubber pads are provided on the new grinder, or the new grinder has new rubber buffers . -Connect the electrical connectors of the grinder motor , the open Seiteder blade receptacle must show due to a possible later release to the outside . Please refer to the polarity of the subsequent pictures and tips .

If the terminals of the new grinder motor are not marked with plus and minus, the same can be determined using the following method: Look at the grinder motor from the bottom with the ground coffee outlet to the top. Divided the bottom in 2 halves with imaginary yellow line. The left half is ( shown in red ) is the +ve contact and the right half ( shown in blue) is the -ve contact. Another method used for +ve connection is by looking on the side of the motor ( see circle in red on the image to the right) .
-Insert the 3 rivets into the rubber buffer and place the grinding unit in the housing while paying attention to the wires, so that they are not pinched / damaged. Fasten the grinding unit with the 3 screws Torx 10th. (use gentle force to tighten !
-Before further assembly, check the rotation of the motor. The motor spins clockwise. Replace the cover on the machine & on the bean container. Cover the openings of the IR - bean monitoring some crepe or tape (no transparent tape ! )

We see extensive Calcium deposits in almost every espresso machine we open for repairs. Filter cartridges are preventative, expensive & ineffective as descaler. The Brita filter installed on the kitchen faucet works better than expensive Jura filters. Calcium sediment inside the machine cause the following problems: (1) reduces flow of water with full or partial clogging. (2) generate back pressure in the Hydraulic system & cause internal leaks. (3) reduce pump pressure, reduce flow of coffee & water for coffee collects in drain tray instead (4) Error codes "Fill water" or Ventilate will display & force expensive repairs. Descaling is best done manually, every two or three months. Order Best descaler (#DSC-6) from our online store for effective & authentic descaling.
